Please forgive me for being pedantic, but the American Cemetery you mean is not in Holland. It’s in Margraten, in the province called Limburg in the southeastern part of the Netherlands.
The Netherlands has 12 provinces, 2 of them are North-Holland and South-Holland, but somehow people (including Rick Steves) refer to our entire country as Holland instead of the Netherlands. Some Dutch people, certainly the ones from North or South-Holland, won’t mind when you refer to them as being from Holland. Others, for instance the proud Limburgers, will object. To them “Holland” feels far away physically and mentally as well as culturally.
With that said. I can certainly understand that you want to honor your fallen countrymen by visiting the cemetery. However, given it’s location all the way down in the southeastern part of our country, the American Cemetery in Margraten won’t be easy to reach on your own before the tour. If you really have your heart set on visiting that cemetery, the easiest way would be to rent a car in Bruges. The drive should be around 2.5 hours one way, depending on traffic.
Another option is to take the train from Bruges in Belgium to Maastricht in the Netherlands and to then take a taxi to the cemetery. The train ride down will be just under 4 hours, one way, with one easy change of train in Liege. The subsequent taxi ride should be around 15 minutes.
